[Vwdiesel] overheating redux

[The President]

Shalyn
It's clear the problem you have...
It's your explosive seat belts!
What has happened is that whilst working on them they exploded and you are 
now in heaven...
[or more specifically VW hell]

>at the coolant reservoir hose.  At least I don't think so.  The memory's
